WESTMONT, IL—After successfully demonstrating the productivity of an open architecture, JDF-based workflow at Graph Expo, Printcafe Software and MAN Roland are planning to take it into the field. The first beta testing with printers is scheduled for the beginning of this year. The interface shown at Graph Expo was a bi-directional link, providing a two-way conduit for data flow. JDF files from the Printcafe system were transferred to a Roland 500 press, supplying job parameters and presetting color. At the same time, the press' PECOM system reported on its progress to Printcafe, via JMF (Job Messaging Format) files. (www.manroland.com/www.printcafe.com)
